MILK-AERATO R.

SPECIFICATION forming part of Letters Patent N o. 694,296, datedFebruary 25, 1902.

Application filed September 10l 1901l Serial No. 74,879. (No model.)

To all whom, it may concern,.-

Beit known that I, LEWIS E. MORGAL, a citizen of the United States,residing at Washington, District of Columbia, have invented certain newand useful Improvements in Milk Aerators, Purifiers, and Coolers; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, which form a part of this specification.

This invention has relation to milk aerators, purifiers, and coolers;and it consists in the novel construction and arrangement of the parts,as hereinafter described.

The object of the invention is to provide an apparatus adapted toaerate, purify, and to cool milk and other liquids. This is done bymeans of forcing a blast of cold air through a falling stream of theliquid, which thoroughly aerates the latter, blowing allim puritiestherefrom and cools it.

In the accompanying drawings, Figure lis a longitudinal sectional viewof the device. Fig. 2 is a transverse sectional View cut on the line 2 2of Fig. 1. Fig. 3 is a transverse sectional view cut on the line 3 3 ofFig. l. Fig. 4 is a transverse sectional view of the device cut on theline 4 4 of Fig. 1.

The apparatus consists of a tank 1, which is adapted to hold the liquidto be treated. The said tank is provided with a slanting bottom 2, andat one side is provided with a cock 3, which enters the tank at thelowest point of the bottom. The tank 1 is removable and is normallyplaced over the chamber 4. Said chamber is adapted to hold ice or water.The top of the apparatus is provided with a trough 5, having in itsouter side a screen 6. Said trough is adapted to receive the fluid fromthe cock 3. The inclined sides 7 are hollow in their interiors andextend down from the trough 5 and have supported between them theshelves S. In the form of the invention shown the shelves 8 are hollowand connected at each end with the hollow interiors of the inclined side7. The shelves 8 are arranged on an incline with relation to each other,each shelf slanting downward toward its outer edge. At the lower end ofthe side pieces 7 a trough 8' is arranged, said trough having aninclined bottom 9, which leads back to a receptacle 10, from which theliquid can be conducted to suitable vessels. The revolving fan 14issuitably mounted on a shaft under the chamber 4.

In operation the device works as follows: The liquid is placed in thetank 1, the chamber4is filled with water and ice, and the fan 14 isstarted in motion. The liquid is permitted to run through the cock 3into the trough 5. In passing through the screen 6 it is thoroughly7screened and the solid particles of matter are removed from it. Theliquid then falls down over the shelves S into the trough 8', and thenruns along the inclined bottom 9 into the receptacle 10. At the sametime a blast of cold air is forced by the fan 14 between the shelves 88. The blast passing through the iiow of liquid falling from the outeredges of the shelves thoroughly aerates the liquid, removing all smell,and the chill from the water contained by the shelf and the side piecescools the liquid. It will thus be seen that the liquid is thoroughlypurified, aerated, and lcooled.

I provide a tank 15, as shown in dotted lines in Fig. l, which canreceive cool water from a spring or any other source, and this water isconducted by means of the pipe 16 to the .upper edge of the lower shelf8, the

water passing down the said shelf, then up through the pipe 16 to thenext shelf, and so on through all of the upper shelves. It will thus beseen that as the milk is descending over the shelves the cool water isascending through them, the advantage of which is that the lower shelveswill at all tim es be the coldest. In the dotted lines shown in Fig. 1,17 is the discharge-pipe, 18 is the receptacle for the discharged Water,19 is the belt-wheel of the fan, 2O is the wheel at which power isapplied, and 2l the belt.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

1. An apparatus of the character described consisting of a series ofhollow shelves over which a liquid is adapted to flow, hollow sidepieces supporting said shelves and opening into the hollow interiorsthereof, said hollow IOO side pieces forming guides for the liquid, ameans for supplying a cooling fluid attached to the apparatus and ameans for forcing air through the liquid as it passes from shelf toshelf.

2. An apparatus ofthe character described, consisting of a series ofhollow shelves over which a liquid is adapted to flow, hollow sidepieces supporting said shelves and opening into hollow interiorsthereof, said hollow side pieces forming guides for the liquid, a lneansfor supplying a cooling fluid attached to the apparatus, a pipeconnecting said cooling means with one of the hollow side pieces, adischarge-outlet attached to the opposite hollow side piece, and a meansfor forcing air through the liquid as it passes from shelf to shelf.

3. An apparatus of the character described, consisting of a series ofshelves over which a liquid is adapted to flow, each shelf beingvdownwardly inclined at its outer edge, each shelf being hollow initsinterior and adapted to contain a cooling liquid, each shelf being ofgreater breadth than thickness, thereby affording an extensive surfacecoming in contact with the cooling medium, and the liquid to be treated,said shelves being arranged one above the other, the general line of theshelves being at an acute angle, a means for supplying a cooling fluidattached to the apparatus and a means for forcing'air through the liquidas it passes from shelf to shelf.

4. An apparatus of the character described,

consisting of a series of hollow shelves ,over which a liquid is adaptedto flow, a means for supplying a cooling fluid consisting of an elevatedtank, a pipe connecting said tank to the lowest shelf, a series of pipesconnecting the shelves together, a discharge-outlet attached to thehighest shelf, and a means for forcing air through the liquid as itpasses from Ashelf to shelf.

5. An apparatus of the character described, consisting of a series ofhollow shelves over which a'liquid is adapted to flow, each shelf beingdownwardly inclined at its outer edge, each shelf being hollow in itsinterior and adapted to contain a cooling medium, each shelf being ofgreater breadth than depth, said shelves being arranged one above theother, the general line of the shelves being at an acuteA angle, a meansfor supplying a cooling fluid consisting of` an elevated tank, a pipeconnecting said tank with the lowest shelf, a series of pipes connectingthe shelves together, a discharge-outlet attached to the highestshelf,and a means for forcing air through the liquid as it passes from shelfto shelf.

In testimony whereof I affix my signature in presence of two witnesses.
